About the Inc. 5000
The Inc. 5000 list is the most prestigious ranking of the fastest-growing private companies in America. Companies are ranked according to their percentage revenue growth over three years.
For K1 portfolio companies, this recognition reflects the hard work of their teams, the strength of their products, and the value they deliver to customers across enterprise software markets worldwide.
The portfolio companies listed represent all current and former K1 portfolio companies named to the 2026 Inc. 5000 list and do not represent all investments made by K1. They are presented for informational purposes only to illustrate K1’s historical investment activities. The Inc. 5000 is compiled annually by Inc. Magazine based on percentage revenue growth over a three-year period; selection criteria and methodology are available at inc.com/inc5000. The ranking reflects the opinion of Inc. Magazine, is not based on K1 fund performance, and is not indicative of future performance. K1 did not pay compensation for inclusion in the ranking. It should not be assumed that the portfolio companies listed were or will be profitable, and there can be no assurance that future portfolio companies will be similar in quality or performance. Past performance is not necessarily indicative of future results. There can be no assurance historical trends will continue. See k1.com for full disclosures.
